Lund University invites applications for a doctoral project on the evolution of colour vision in marine invertebrates. The PhD researcher will investigate whether the firefly squid, a cephalopod, and the alciopid worm, an annelid, have independently evolved colour vision despite living in deep-water, night-time environments. The project will examine how colour vision influences behaviour and whether these species use visual processing circuits and principles comparable to those found in arthropo...

PhD opportunity in Neuroscience, Molecular Biology, and Behavioural Biology at the Medical Research Council Laboratory of Molecular Biology (Cambridge, United Kingdom). This project, supervised by Dr W Schafer, focuses on neuropeptide networks and how “wireless” neuronal communication shapes behaviour. The first part uses C. elegans to study neuropeptide signaling in feeding circuits, including how peptides and receptors related to human hypothalamic appetite pathways regulate feeding and starva...

About this position

This doctoral project is based in the Bok Lab at Lund University and sits within the Lund Vision Group, a collaborative research environment focused on comparative visual science across the animal kingdom. The group brings together several labs and a broad mix of expertise, with work spanning jellyfishes, insects, crustaceans, squids, and vertebrates. The environment combines optics, electrophysiology, theoretical modelling, microscopy, molecular biology, and behavioural experiments to investigate how eyes evolve, how vision supports navigation and behaviour, and how visual systems are adapted to different habitats and lifestyles.

The PhD project asks whether colour vision has convergently evolved in two unusual marine invertebrates: the firefly squid and the alciopid worm. Both are deep-water, night-active species with striking retinal specializations, and the project will test whether these traits support colour vision and what behaviours may be controlled by it. The student will work across field and laboratory settings, using behavioural assays, molecular approaches, neuroanatomical mapping, and electrophysiology to explore visual function and evolution.

Research activities include behavioural experiments at field stations in Italy and Japan, transcriptomic-based localization of photoreceptor and visual interneuron classes, connectomic mapping of retinal and optic lobe circuitry, and electrophysiological work to identify neurons involved in colour and polarization processing. The project is embedded in ongoing Bok Lab research on complex eyes and visual capabilities in crustaceans, cephalopods, and polychaetes, and the student will benefit from guidance from the lab’s postdoctoral researchers and from links to Sensory Biology and Aquatic Ecology units. The broader setting is a well-funded and active research group with extensive international collaboration and opportunities to present work at conferences.

What's required

Applicants must have a second-cycle qualification, or at least 240 credits with at least 60 credits at second-cycle level, or equivalent knowledge. For Biology doctoral studies, the applicant must have completed an independent work (for example a degree project) worth at least 30 higher education credits in a relevant subject and have good oral and written English. The position additionally requires a Master’s degree in biology or marine biology, or substantially equivalent knowledge, practical experience with animal vision behavioural experiments, fieldwork-based research experience, the ability to work independently and solve research problems, strong written and oral communication skills, ability to cooperate well with colleagues and collaborators, and very good English.

How to apply

Apply in English through the Lund University application portal. Attach a CV, a personal letter explaining your motivation and fit for the project, copies of degree certificates and transcripts, and any other supporting documents such as grades, references, or recommendation letters.
